If the optional controller pop-up status is enabled when the QX351detects battery failure, a pop-up status
dialog is displayed on the current screen to alert the operator of the Ok status change. The operator can
then invoke the system menu diagnostic sub-menu to determine the cause of the loss of Ok status.
Alternately, the screen designer can also place a graphic object or audible indicator (through ladder logic)
in the application (referenced to OCS register %SR55.13) to alert the operator of battery failure.
It is also suggested that the System Menu diagnostic sub-menu battery indicator be checked on a regular
basis to verify its operation.
